Perl as DSO...whats wrong with it, specifically?
I'm working with IBM (sorry! Its not my choice!) to try to get mod_perl compiled into their custom version of Apache, and their techs want to know why I can't run mod_perl as a DSO. So, I need to know, whats specifically wrong with it? Like, what are the repurcussions of it? This is going to be run under a lot of load as well.
Thanks for your feedback in advance.

I am running mod_perl as a DSO on AIX and it works fine with the
exception of a memory leak on each apachectl restart. As a workaround I
use a real stop every few weeks to get the server memory footprint back
to normal.

As long as you have the latest version of mod_perl (probably from CVS)
you're ok I think. I have no trouble with it on a BSD/OS system
whatsoever.
Others may disagree...
I think it also depends on your OS.

Well, it works now in most cases, if you use the current version. It's
not necessarily a good idea if you're dealing with x86 (it has to be
built PIC, and thus increases register pressure). But other than the
slight PIC slowdown it hasn't caused problems in a few months.

I run mod_perl as a DSO without a problem. Just don't try to mix it with php as
a DSO.

Oops, the build process appears to be rather broken in the AIX case
without APXS, this needs fixing. Does anybody know why there are so many
ways to build mod_perl? And what is actually the most important way to
build it? I always assumed the apxs way by touching the least of Apache
is to be preferred.

Oops - I did misread, you said you are using 1.24.

Since the problem appears the improper definition of the export file (I
believe mod_perl.exp) I tried to link it by hand - but I don't understand
the .lo files. I also tried changing -bE:$(BASEEXT).exp to
-bE:mod_perl.exp. Neither of these helped.
I haven't messed w/ apxs much yet - but will try it when i have time. (my
mod_perl problems have actually taken back seat at the moment)
thanks for all your alls help!

In general - all of the previous threads on this topic have either gone
off-list or were never resolved.
I spent several weeks trying various configurations w/ mod_perl-1.24 &
apache 1.3.12 on an AIX 4.3.3 box running perl 5.00503 and using xlc as my
compiler.
I was never able to successfully compile a DSO mod_perl.
However, most of the versions have a patch that needs to be applied to the
dynamic loader code in perl. perl needs then to be recompiled before
building mod_perl.
even w/ these patches I was unable to build it successfully. I tried to
use perl 5.6 as well - but ran into more problems (unrelated?) then I had
w/ 5.00503.
I wish I could offer you some secret key - but for me it has been a
constant source of frustration.

is this the continuation of a thread, or a new question?
this has come up a lot in the mailing list.. have you checked the
